These scissors are "Perfect" because they have a micro serrated blade that keeps fabric from slipping so cutting is more accurate. All KKB scissors come with a plastic cover that keeps the tips from being damaged when not in use. The soft handles are larger than most scissors of this size and prevent soreness when using for an extended period of time. These scissors cuts 4 to 6 layers of cotton fabric easily. Some of our customers prefer to use this size for their fusible applique. Try all of the sizes. You will love them!
